VLAN Features

The Cisco uBR7200 Series support the following VLAN feature:
•
HSRP over ISL in Virtual LAN Configurations
Inter-Switch Link protocol (ISL) is a Cisco protocol for interconnecting multiple switches and
maintaining VLAN information as traffic goes between switches. ISL provides VLAN capabilities while
maintaining full wire speed performance on Fast Ethernet links in full- or half-duplex mode. ISL
operates in a point-to-point environment and will support up to 1000 VLANs. You can define virtually
as many logical networks as are necessary for your environment.
For configuration information for Hot Standby Router Protocol (HSRP) over Inter-Switch Link (ISL)
protocol, refer to these documents on Cisco.com:

VPN and Layer 2 Tunneling Features

The Cisco uBR7200 Series supports multiple features and functions for virtual private networks (VPNs),
to include the following:
•
•
•
•
•
•
•
•
Dynamic SID/VRF Mapping Support
Cisco IOS release 12.3(13a)BC introduces support for dynamic service ID (SID) and VRF mapping on
the Cisco CMTS, to support VoIP with MPLS. Formerly, the MPLS SID mapping feature only applied
to provisioned service flows. This feature enables the mapping of all PacketCable DQoS service flows
to one particular VRF.
